Does the trapezius flex or extend the neck?
The traps laterally flex the head and neck, rotate (turn) the head to the opposite side (so if you look to the right, your left upper trap is contracting) and when both the left and right upper trapezius muscles fire together, they extend the head and neck.
Does trapezius do flexion?
Action. Unilateral contraction: Ipsilateral side flexion of neck. Middle part: assists with ipsilateral side flexion and contralateral axial rotation of upper thoracic region.
What muscle is flexion of the neck?
scalene muscles
The scalene muscles help with neck flexion and side bending. The deep cervical flexors are a muscle group consisting of the longus capitus and longus colli muscles, which run down the front of the cervical spine. The deep cervical flexor muscles help flex the neck forward as well as stabilize the cervical spine.
What muscles extend the neck?
Sternocleidomastoid: One of the largest muscles in the neck, helping you move your head, extend your neck and control your temporomandibular joint (in the jaw). It begins just behind your ear and stretches to your collarbone.
What muscles are involved in neck flexion and extension?
Muscles of the Spinal Column
| CERVICAL MUSCLES | FUNCTION | NERVE |
|---|---|---|
| Sternocleidomastoid | Extends & rotates head, flexes vertebral column | C2, C3 |
| Scalenus | Flexes & rotates neck | Lower cervical |
| Spinalis Cervicis | Extends & rotates head | Middle/lower cervical |
| Spinalis Capitus | Extends & rotates head | Middle/lower cervical |
Is shrugs push or pull?
The shrug is considered a pulling motion, as the weight is lifted toward the center of the body during the concentric phase of the primary muscle group. This exercise is also considered of basic utility, as a greater intensity is placed on the muscles than with smaller auxiliary exercises.
Which muscles assist in the flexion and rotation of the neck and are involved in traumatic whiplash injuries?
The sternocleidomastoid muscles are located deep to the platysma. They are individually responsible for flexion of the neck to the ipsilateral, or same, side and rotation of the neck to the contralateral, or opposite, side.
Why are my traps always tense?
A very common posture we see in people coming in for UT “tightness” is a depressed (lowered) or protracted (hunched forward) shoulder blade, and this is usually associated with a rotated posture somewhere else in the body. This causes the UT and other neck/shoulder muscles to become imbalanced.
